Household Fence from firewood. DIY. Part 1

I have long wanted to make a fence in front of the house so that flowers do not fall on the path located next to it.
For production I chose one of the most durable types of wood - larch.
Unfortunately, I have no money for new boards yet, but I have old formwork boards and pallets.
In the process of preparation, I will show you a method for finding broken screws in old boards.
I will show you what method I use to seal the seams and cracks in them.
All elements of the connection of joints in this structure are reliable, and the pillars do not swing over time.
This is the first - the preparatory part, for the manufacture of the adjoining fence.
I wish you a pleasant viewing.
